2025 Chevrolet Silverado 3500 HD Maintenance Schedule
    7,500-Mile Service
    During your vehicle’s initial 7,500-mile maintenance visit, our certified service technicians will perform an oil change, lubricating engine components and preventing premature wear. Neglecting regular oil changes can lead to significant engine issues over time. Consider scheduling oil changes more frequently if your driving habits include frequent towing or heavy hauling.

    In addition to the oil change, our technicians will inspect and rotate the tires to promote even wear and extend tire life. They’ll also examine the brake system to ensure all components function correctly. These services help preserve performance and reliability and are included in every scheduled service visit.

    22,500-Mile Service
    Upon reaching 22,500 miles, the cabin air filter will be replaced to maintain air quality inside the vehicle by filtering out dust, pollen, and other airborne particles. A clogged filter can reduce airflow and may cause discomfort for occupants.
    During this service visit, our service technicians will also replace the transmission fluid to ensure smooth gear shifts and prevent transmission wear. For models equipped with four-wheel drive, it’s also necessary to change the transfer case fluid to maintain proper lubrication and functionality of the drivetrain components.

    45,000-Mile Service
    At the 45,000-mile mark, our service technicians will replace the engine air filter. A dirty or clogged filter can restrict airflow to the engine, leading to decreased performance and fuel efficiency. The brake fluid will also be changed during this visit. Brake fluid can absorb moisture over time, which can cause corrosion within the braking system and reduce braking effectiveness. Additionally, our service team will inspect the evaporative emissions control system to ensure it’s functioning correctly, preventing fuel vapors from escaping.

    97,500-Mile Service
    At 97,500 miles, it will be time to replace the spark plugs. Worn spark plugs can cause engine misfires, rough idling, and decreased fuel efficiency. Replacing old spark plugs ensures the engine will continue running smoothly.

    150,000-Mile Service
    When the truck hits 150,000 miles, the cooling system will need fresh coolant to keep the engine from overheating. Flushing out the old coolant and refilling it helps maintain proper temperature regulation and prevents corrosion inside the system.
